Find the median and the range of the given data set.

7, 8, 20, 6, 9, 11, 10, 8, 9, 8


  1. Answer:

    median = 8.5

    range = 14

    Step-by-step explanation:

    To get the median orser the date in ascending order then use this formula to find the position of the first value in the median since the amount of values is an even number: n÷2.

    You’ll find that the answer is 5 (10÷2=5) so the second value is the one after it, the 6th value.

    The 5th and 6th values are 8 and 9. Add these values and divide that answer by 2 to get the final answer of 8.5 [(8+9)÷2]

    The range is the difference between the largest value of data and the smallest. (20-6=14)
